Video processing device and method

Abstract

The invention discloses a video processing device and method. The device comprises a dual-matrix selecting module and a dual-channel color data processing module. Due to the adoption of the dual-channel color data processing module, an odd set of pixel data and an even set of pixel data can be processed at the same time in one clock cycle; due to the fact that two shaking matrixes are adopted when two adjacent frames of images are displayed, the structure is simple, and the processing speed is high. The two-frame circulation algorithm cycle is used in shaking in time, the 2*2 shaking matrixes are used in shaking in space, and the effect that 8 bit video data are formed through 6 bit display data in a shaking mode is achieved. Furthermore, due to the fact that the two shaking matrixes are adopted, the display performance of a displayer can be improved, the odd set of pixel data and the even set of pixel data are processed at the same time in one clock cycle, and the working frequency of a circuit is reduced.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to a video processing device and method. Background technique [0002] Generally, the video signal sent by the computer graphics card is 8-bit data, so that each color channel can display 256 gray scales. If the signals controlling R, G, and B on the panel are also 8-bit, it is called 8-bit. Bit panel, that is, true color panel. Since a pixel is composed of three color channels of red (R), green (G), and blue (B), on an 8-bit panel, each pixel can display 256*256*256 colors. But now 8-bit panels are more expensive and the process is more complicated, so most panels are 6-bit. Can display 64*64*64 colors. [0003] It can be seen from the above data that physically, the color displayed by the 6-bit panel is less than 2% of that of the 8-bit panel. If no processing is performed, the 6-bit display will definitely not meet people's requirements. In the prior art, a 6-bit pan...

Problems solved by technology

Dithering has been done in space, but in terms of time, the gray value of the same point remains unchanged. There is no color mixing in time, which will give people a visual experience of block effect, resulting in poor display performance of LCD

[0007] To sum up, when the existing technology uses a 6-bit controller to control the R, G, and B signals respectively to achieve the display effect of 8-bit video data, the display performance of the display is poor
